Akribis SGR Rod Motor Modules With Optical Encoder Deliver Submicron Positioning Accuracy

August 28, 2024
Akribis SGR Series

In rapidly evolving sectors such as semiconductor, biotechnology, precision assembly, and battery manufacturing, the trend towards smaller and faster equipment and systems necessitates that positioning stages evolve accordingly.

These stages must not only achieve higher operational speeds but also deliver the micron-level precision that these increasingly miniaturized applications demand, while maintaining a compact format.

Here are some of the advantages of the Akribis SGR rod motor module.

  • Direct drive motors. These motors are characterized by a high torque constant that gives them higher accuracy and repeatability.
  • Ironless construction. Without attraction between the motor and magnets, strokes are consistent and cog-free.
  • Consistent force production. An air gap between the coil and magnet — such as in rod motors — reduces wear and ensures force consistency.
  • Shaft motor design for high efficiency. Motors with a tubular design distribute magnetic flux evenly along the circumference of the stator for greater efficiency. The result: less heat generation and higher accuracy.
  • Optical incremental encoder. Compared to other feedback technologies, contact-free optical incremental encoders provide optimal resolution and higher accuracy.
  • Compact size. Space is typically at a premium in applications like semiconductor and biotechnology equipment.

These characteristics play a crucial role in achieving the micron positioning accuracy motion systems require in dynamic sectors.

The SGR Series by Akribis Systems is the perfect positioning module for rapid point-to-point positioning in high-speed, high-precision applications.

The unit features a coreless direct drive rod motor from the Akribis RDM-A Series, along with a linear guide rail and an integrated encoder.

With stroke lengths ranging from 70mm to 720mm and an encoder resolution of 0.2 µm, the SGR Series provides continuous force (Fcn) between 3.1 and 114.8N, and peak force (Fpk) from 9.3 to 344.5N, ensuring remarkable positional accuracy and repeatability.

Its applications extend to sectors such as glass and LCD panel manufacturing, medical devices, printing machinery, laser processing, and precision assembly.
